Hello monks,

I'm currently writing a wrapper to run another program. Now i run the program N times and reformat its output into another format. However the program that I run seems to output some useless lines into STDERR and i would like to get rid of these. I run the program like this: 
# @exec has the commad that i wish to run
open (T_RES,"@exec |") or die "Unable to fork '@exec': $!";
while (<T_RES>) {
  # parsing the output
}

[download]
This allows the output parsing to read the T_RES as a file, which don't require me the save all the output into memory. However this way does not capture the STDERR. Is there a way to capture the STDERR in this way as well? Is there another way which would be as easily used and require little memory?
